如果你的架构和有效架构都是正确的，你可以检查你是否添加了$(inherited)，它将在pods中生成的链接器标志添加到其他链接器标志，如下所示:

添加“Security.framework”对我来说很管用。

当我在构建第二级框架时，我的“伞形框架”遇到了这个问题。

我通过改变我的第一个关卡框架的“通用iOS设备”构建方案来解决这个问题。我认为这将改变_CodeSignature，当我把我的整个“伞形框架”推到GitHub时，我看到了差异。

问题是cocoapods还没有为arm64架构构建，因此当你构建它们时，它们不能链接。在更新并使用该体系结构之前，您可能无法使用这些包。您可以通过进入项目->目标(您的项目名称)->构建设置并将架构更改为标准架构(armv7, armv7s)，并将有效架构更改为armv7, armv7s来修复链接器错误。

Note though, this means you won't get the full power of the 64 bit processor. You said you are building for the 5s, so there may be some reason you need this. If you for some reason absolutely need that power (perhaps you are building a game), and desperately need those files, you could submit a pull request and then recompile the project to arm64 by setting those same fields to arm64 in the files you pulled from the open source projects. But, unless you really need these files to be 64 bit compatible, that seems like a bit of overkill for now.

编辑:有些人还报告说，将为活动架构构建设置为YES也是解决这个问题的必要条件。

截至2014-04-28，设置应该是这样的:

为了克服这个问题，我在安装AWS框架后也遇到了同样的问题，我更新了安装AWS POD后创建的项目中的POD配置文件。检查配置文件如下所示

OTHER_LDFLAGS = $(inherited) -ObjC -l"Pods-AWSAutoScaling" -l"
Pods-   AWSCloudWatch" -l"Pods-AWSCognito" -l"Pods-AWSCore" -l
"Pods-AWSDynamoDB" -l"Pods-AWSEC2" -l"Pods-AWSElasticLoadBalancing"

-framework "CoreLocation" -framework "Foundation" -framework
"ImageIO" -framework "Security" -framework "SystemConfiguration"
-framework "UIKit" -weak_framework "UIKit"
 OTHER_LIBTOOLFLAGS = $(OTHER_LDFLAGS)   

如果你的配置文件不能正常工作，那么将你的其他链接标志设置为$(inherited)

在我使用dlib在IOS的情况下，我需要删除“继承”从构建设置/预处理器宏。
